County Board to act on letter supporting I-88, Route 47 interchange

GENEVA – The Kane County Board is expected next week to consider a document declaring its support of an upgrade to the Interstate 88 interchange in Sugar Grove.

On Wednesday, the County Board’s Executive Committee advanced a letter of intent between the county, Sugar Grove, the Illinois State Toll Highway Authority and the Illinois Department of Transportation about the proposed I-88 at Route 47 interchange expansion.

The letter – a copy of which is on file at the Kane County Clerk’s Office – will serve as a basis for the development of a future intergovernmental agreement for the project. IDOT drafted the document.

Kane County Deputy Director of Transportation Tom Rickert said at a committee meeting last month that the letter would not commit the county to any funding at this point.

Turning the intersection into a full interchange is expected to cost about $20 million, with IDOT contributing 25 percent of the cost and the tollway paying for 50 percent, officials have said.

Sugar Grove and Kane County would address the remaining costs.

The project is about five years out from the beginning of construction, officials have said. The letter of intent will help move the first phase of engineering forward.
